BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention is directed to ways to create and manage websitesand their content. More particularly, the invention is directed to anobject-oriented way to create and manage dynamic websites and theircontent.

2. Description of the Related Art

Today, web pages and their content are typically created, managed anddelivered using a variety of tools and systems. Programming tools (e.g.Adobe Dreamweaver™) are commonly used for web page creation, andauthoring tools (e.g. Microsoft Word™ or Adobe PhotoShop™) are commonlyused for content creation. Content Management Systems (e.g. Drupal™ orOpenCMS™) may also be used for controlling and transforming contentafter it has been created, and version control systems and database andweb servers are used for storing and delivering the web pages and theircontent to end user browsers.

While in some cases it may be valuable from a “separation of concerns”perspective (i.e. having the creative department use one set of tools,and the IT department use others), the use of tools and systems that arenot integrated makes it necessary to integrate the work product of eachdepartment in a separate, final step to permit a given web page and itscontent to be published to the Internet. One problem with this approachis that it is time consuming, and this problem is exacerbated by thetendency that websites (and their content) are rarely static. Almost allwebsites change frequently, being updated constantly to reflect changesin the organization or individual publishing the website or in its (orhis/her) environment.

The absence of an integrated system makes creating and revising contentand a set of web pages on a website (or on any given web page of awebsite) unduly difficult in terms of both effort and complexity. Oncedesign mock-ups and digital assets (e.g. art, photos, and videos) havebeen developed, the website's web pages are built with these designelements using HTML, CSS and JavaScript programming languages to achievethe effects called-for in the design. Next (or in parallel), newsarticles, product data sheets and other information are developed toform the content for the site.

At this point the user faces a choice of whether or not to use a ContentManagement System (a “CMS”). Content Management Systems are typicallyemployed if the content on a website is expected to change frequently.If not, then the website publisher will typically “hard-code” thecontent directly into each web page file.

If a CMS approach is chosen, the next step is to place all content itemsinto a relational database, and to turn each web page file (viaprogramming) into a “page template” that is bound to the CMS. The CMSthen dynamically (or, in some systems, statically during a compilationprocess) creates individual web pages of a website by combining thecontent in the database with the layout, presentation and behaviordefined in the web page template. At this point, the final web page isready for delivery to an end user's browser.

A significant problem with the technologies and processes describedabove is that it is very difficult to build and integrate all of thecontent and web page (i.e. layout, presentation, and behavior)components needed for a sophisticated website. If a CMS is employed tomanage content changes, the initial build is even more difficult, andeven if a CMS is employed, it is still very difficult to make subsequentchanges to site structure (“site map”) and web page components withoutinvolving considerable programming.

For illustration, consider this simple example:

Without a CMS, combining content and web page visual aspects (layout,presentation and behavior) may be done like this using HTML andJavaScript:

<body>  <div> style=“background-color: yellow”;onclick=“showMenu(someElementID)”onmouseover=“this.className=fredHighlight”onmouseout=“this.classname=“fred” class=“fred”> <p>

This is some text

</p> </div> </body>

The above code would produce a section on a web page with a yellowbackground color (layout and presentation) as well as set up some codeto handle mouse clicks, etc. (behavior). Finally, it would display theline “This is some text” (content) on the page.

Using a CMS, the above code would become:

<body> <div> style=“background-color: yellow”;onclick=“showMenu(someElementID)”onmouseover=“this.className=fredHighlight”onmouseout=“this.classname=“fred” class=“fred”> <p> $Content </p> </div></body>

The term “$Content” is a variable whose value (e.g. “This is some text”)is defined and stored in a database that is populated by the websitepublisher. If the value of $Content is indeed “This is some text”, thenthe CMS code above would produce, from the end user browser'sperspective, exactly the same web page and content as the non-CMS codeabove. However, note that by implementing the CMS, the content in thedatabase could be changed to any value (say, for example, “Hello World”)and this would be automatically displayed on the web page the next timeit is rendered.

The CMS approach therefore provides an improvement relative to the hardcoding of all content into individual web pages in situations where thecontent is expected to change relatively frequently. However, the CMSapproach also has significant drawbacks in that it does not facilitatechanges in web page visual aspects. What if, for example, a websitepublisher wants to change the background color, or more interestingly tochange what happens when the end user browser clicks or hovers oncertain elements within a web page? How would the publisher adds anentirely new web page to display new content?

Changes of this sort are examples of changes to web page visual aspects(including structure, layout, presentation and behavior), and cannot beimplemented using current technologies without additional programming.

SUMMARY OF THE INVENTION AND ADVANTAGES

The present invention is addressed to these challenges.

The following summary provides a simplified overview of the subjectmatter that is described herein, and is not intended to identify anycritical elements, nor to delineate the scope of the described orclaimed subject matter. The sole purpose of the summary is to outline ina simplified form the aspects of tile subject matter that will bedescribed in greater detail below.

Briefly described, the subject matter disclosed herein relates invarious embodiments to systems and methods that support the creation andlifecycle management of all the attributes and methods contained withina typical website in a completely object-oriented manner, such thattraditional web programming languages, version control and contentmanagement systems are not required. A three tier approach is applied,providing a presentation tier, a logic tier and a storage tier.

At the presentation tier, some of the objects created and managedinclude:

-   -   Sitemap and Navigation    -   Pages and layout    -   Page elements (aka widgets)    -   Forms and database views    -   Style, and    -   User event (mouse clicks, key presses, etc) handling

At the logic tier:

-   -   Business rules, including workflows, and    -   Server-side event handling

And at the storage tier:

-   -   Configuration and object persistence    -   Structured (headers, footers, body text, lists, blogs, news        items—generically “content”) and non structured (e.g., PDF        files) user data storage    -   User defined tables, and    -   Search and retrieval of stored data

In contrast to existing website production and delivery systems, thesystem and method described herein allows each object to be managed(created, updated, versioned) separately from each other, whileretaining the relationships (containment, parent, child, sibling, is a,etc.) between the objects. For example, a content display object and itsrelationship to content items and pages that may contain it.

With this object-oriented design, objects within a website can becreated and changed independently from each other without requiringtextual programming. Objects are created and configured via a drag/dropor fill-in-the-blank metaphor, as are their behaviors andinter-relationships (e.g. Page to element, Form to table, table tofields, etc.).

According to one aspect of the present invention, there is taught amethod of creating and managing websites and their content by providingon a system server a plurality of hierarchical classes of objects, eachof the classes representing one aspect of the storage, presentation andlogic of a website; providing on a web server an interface operable topresent representations of objects instantiating the plurality ofhierarchical classes, and receive commands meant to one of instantiate anew object, destroy a presented object, and change a property of apresented object; and storing on a database server objects as atraversable tree in accordance with the plurality of hierarchicalclasses.

The method further provides for rendering a requested portion of thewebsite by traversing the corresponding portion of the object tree andgenerating a dynamic webserving in response to the properties of thetraversed objects.

Providing an interface might include providing a user-interface or evenproviding a WYSIWYG user-interface. In that regard, presentingrepresentations of objects might include presenting symbolicrepresentations of objects.

Receiving commands might include receiving user-inputs.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION Introduction

Referring to the Figures, like numerals indicate corresponding partsthroughout the several views.

FIG. 1 generally illustrates a system for creating and managing awebsite 20 as an object-oriented structure. A website creator 22,website manager 24 and website end user 26 respectively create, manageand use the dynamic website, communicating through their respective webbrowsers 28 with a web server 30.

Terminology

Throughout this specification, the term “web page” refers to the visualaspects of any given page of a website, including layout (e.g. the sizeand location of visual elements or “widgets” on each page), presentation(e.g. style, colors, and format of widgets), and behavior (e.g. whathappens when a user moves a mouse 32, clicks a button or menu, hovers,etc.),

The term “content” refers to the information (e.g. text and graphics,such as, for example, a news article) that is delivered to an end userbrowser 28 via the web pages of a given website.

The term “web serving” means a portion of code—generally somecombination of HTML, CSS and JavaScript—sent from a web server 30 to aweb browser 28 to direct the browser 28 to perform desiredfunctionality, such a presenting a webpage or a portion of a webpage.

Those skilled in the art will understand that in an internetworkedsystem 20 an action is often the result of coordinated activitiesoccurring at multiple nodes in the system 20. In the case of a system 20built on the Internet, these nodes arc often distributed ad hoc andunpredictably across multiple jurisdictions. The act ions as describedand claimed herein arc intended to encompass at least: (a) actionsperformed directly and completely within the jurisdiction of the patent,(b) actions coordinated within the jurisdiction but with at least someactivities performed outside the jurisdiction, (c) actions coordinatedoutside the jurisdiction but with at least some activities performedwithin the jurisdiction, and (d) actions performed for the benefit of anode within the jurisdiction or a person using that node. An example ofsuch coordination would be serving a layout for a web page from one nodeand serving content for insertion into the layout from one or more othernodes, including through the use of server-side scripting, client-sidescripting, and AJAX techniques.

Structure

FIG. 2 is a deployment diagram of the system 20, which is deployed as aninternetwork 34 of communication and computing devices 36. As will bediscussed in greater detail below, the communication and computingdevices 36 are variously configured as clients 38, 40, 42 and servers30, 44, 46. More specifically, a client might be a website creator'sclient 38, a website manager's client 40 or a website end-user's client42. A server might be a web server 30, a system server 44 or a databaseserver 46.

Each of the clients 38, 40, 42 might be a duly configured generalpurpose programmable computer or a more purpose-specific device 36, suchas a smartphone, a microbrowser, or portable media viewer with awireless modem.

A server might similarly be a duly configured general purposeprogrammable computer, but might also be a farm of such computers or oneor more virtualized computers embodied as processes operating on aphysical general purpose programmable computer. Such farmed orvirtualized computers might themselves be distributed over their ownlocal or wide area network 34, not shown.

In essence, the servers 30, 44, 46 and the clients 38, 40, 42 are rolesor functions performed in the system 20 by properly configured devices36. Multiple roles or functions could be performed by one device 36 andone role or function could be distributed over multiple devices 36. Thespecific character of a device 36 (and more generally the hardware) andthe network 34 topology is important to the extent that it supports theperformance of the assigned roles or functions.

The web server 30, system server 44 and database server 46 may beconnected together in three-tier fashion to serve the presentation,logic and data aspects of dynamic websites, the web server 30 and thesystem server 44 communicating in HTML, CSS and JavaScript and thesystem server 44 and the database server 46 communicating in SQL.

The clients 38, 40, 42 may communicate with the web server 30 using theHTTP protocol to interact with the websites. More particularly, thecreator's client may communicate to create a website, the manager'sclient may communicate to manage a website, and the end-user's clientmay communicate to use a website.

To implement this arrangement, the devices 36 each host an operatingsystem 48 that provides an execution Environment supporting the requiredfunctionality. The operating systems 48 might also support distributedexecution among the devices 36.

In this way, the clients 38, 40, 42 each support a browser component 28to implement communication with the web server 30, for example such asMicrosoft® Internet Explorer®, Firefox®, Safari® or Opera®. Thecreator's client and the manager's client might also support an editorapplet component 50 to better implement communication with the systemserver 44 for editing website objects, as will be discussed furtherbelow.

Similarly the servers 30, 44, 46 have dedicated components supported bythe operating system 48 execution environment. The web server 30 has aweb server component 52 that instructs it on how to perform its role asa web server 30, for example Apache® Apache®, Microsoft® InternetInformation Services® or Google® Google Web Server 30®. The systemserver 44 has an object editor component 54 and an object renderercomponent 56 that respectively instruct it on how to create, modify anddestroy objects that represent aspects of a website and to render theobjects into webservings that can be communicated by the web server 30.The database server 46 has a database management system component 58that instructs it on how to create, store, search, maintain and destroyobjects that represent aspects of a website drawn from a website package60 of classes, which will be described further with respect to FIGS.4-7.

FIG. 3 illustrates a common construction of a communication andcomputing device 36, including a general purpose programmable computer.These devices 36 have a hardware layer 62, an operating system layer 64and an application program layer 66. Those skilled in the art willrecognize the aspects in which like virtualized hardware and devices 36depart from like physical ones.

The hardware layer 62 provides the device 36 with computing andcommunication hardware, including: (a) a processor 68 to executeprocesses of instructions and compute data, (b) user-input hardware suchas a keyboard 70 and a selection device 72 (for example a mouse 32) toreceive input from a user, (c) user-output hardware such as a videodisplay 74 to provide information to a user, (d) mass storage 76 such aselectromagnetic, optical or nonvolatile solid-state media to store dataand processing instruction s, (e) memory such as read only memory 78 andrandom access memory 80 to store data and processing instructions, and(f) a network interface 82 to support communication with other devices36 in accordance with known protocols such as TCP/IP, all interconnectedby buses such as address and data buses and control lines such asinterrupt and clock lines and such other connections and components asis conventionally required and known in the art.

Stored in a portion of the read only memory 78 and the mass storage 76arc the components of the operating system layer 64, for example LINUX®or Microsoft® Windows® Server® for a device 36 such as general purposeprogrammable computer configured as a server 30, 44, 46 or LINUX® orMicrosoft® Windows® VISTA® for a device 36 configured as a client 38,40, 42, or even Microsoft® Windows® CE® for a portable such client 38,40, 42 device 36. The operating system layer 64 provides the basicinstructions to direct the processor 68 how to interact with the otherhardware described above and more generally how to perform the functionsof a communication and computing device 36, including storing, accessingand computing data, and communicating with other devices 36.

The operating system layer 64 also presents an application programinterface 84 to the application program layer 66, so the processor 68can execute more sophisticated combinations of processes under thedirection of higher level application programs stored in mass storage 76and loaded into RAM 80 for execution, for example the componentsdescribed in FIG. 2.

FIG. 4 illustrates packages 60, 86, 88, 90 of classes for completelyrepresenting a dynamic website in an object-oriented manner. In thisregard, there is provided a Website package 60 that contains classes andpackages 60, 86, 88, 90 for representing a dynamic website. The Websitepackage 60 contains a Website class 92 that provides attributes andoperations representing the overall nature of a website and furthercontains a Presentation Tier package 86, a Logic Tier package 88, and aStorage Tier package 90 that in turn contain classes that represent moreparticular aspects of the website.

FIG. 5 shows an example hierarchy of classes below the Website class 92for representing presentation aspects of the website and inclusion inthe presentation tier package 86. Thus for example, the presentationtier package 86 could include a User Event Handling class 94 forhandling client-side user-events and a Styles class 96 for specifyingthe style of the website. The presentation tier package 86 could alsoinclude a Navigation class 98, for example, a Sitemap class 100, fordefining ways to navigate the website. The presentation tier package 86might also include a Pages class 102 for defining aspects of eachwebpage, in cooperation with a Layout class 103 for defining visuallayout aspects or the webpage and a Page Elements 104 class forrepresenting page widgets, for example database 58 views and forms asrepresented respectively by a Database Views class 106 and a Forms class108.

FIG. 6 shows an example hierarchy of classes below the Website class 92for representing logic aspects of the website and inclusion in the logictier package 88. Thus for example, the logic tier package 88 couldinclude a Server-Side Event Handling class 110 for handling server-sideevents and a Business Rules class 112 for representing the businessrules that establish the logical operation of the website, for exampleworkflows as represented by a Work Flows class 114.

FIG. 7 shows an example hierarchy of classes below the Website class 92for representing storage aspects of the website and inclusion in thestorage tier package 90. Perhaps most importantly, the storage tierpackage 90 includes a Data Source class 115 to enable objects to beeither local, for example on the website manager's 24 own network, orhosted by a software as a service vendor on the system 20. Thus forexample, the website manager's 24 own network might provide a webapplication that the system 20 can interact with via objects of the DataSources class 115 to allow an end-user 26 to access and interact withthe local application via web pages that are created and managed by thesystem 20. In this regard, “Data Sources” are a class of object in thesystem 20 that sit on top of the data tier and contains and abstractsthe information needed for the system 20 to “bind” to a set of webservices exposed by any web application, which may encapsulate its ownset of presentation, logic and storage tier objects. In the hosted case,objects of the Data Sources class 115 simply point to data objectswithin the system 20. In this way, the website manager 24 can create webpages that render content from data objects that are stored and managedin other business applications that are exposed to the internet via XMLweb services, for example SOAP and REST.

The storage tier package 90 could also include a Digital Assets 116class for representing digital assets 116 and a Databases class 118 forrepresenting databases. The Databases class 118 could include a numberof aggregate classes, including a User-Defined Tables class 120 forrepresenting the data structure, including for example fieldsrepresented by a User Fields class 122, a Search Queries class 124 forrepresenting search queries, and a Search Query Results class 124, 126for representing query results. The storage tier package 90 might alsoinclude an Object Configuration class 128 for representing theconfiguration of objects, including for example object persistence asrepresented by an Object Persistence class 130. Additionally, thestorage tier package 90 might include classes for representing contentfor the website, for example a Content Lists class 132 that represents acataloguing of content items as represented by a Content Items class134. The Content Items class 134 might in turn include a number ofaggregate classes such as a User Data—Nonstructured class representingunstructured data and a User Data—Structured class representingstructured data, for example data having an author, title and body asrespectively represented by an Author class 140, a Title class 142, anda Body class 144.

Those skilled in the art will recognize the hierarchical nature of theclasses and packages 60, 86, 88, 90 contained in the Website package 60,such that traversing the tree of the hierarchy will produce a definitionof the website or of that portion defined by the portion of the treetraversed.

Thus FIGS. 4-7 graphically depict the types of classes within anexemplary system 20 and the relationships between them. Many sites, aswell as their child objects, can be hosted and managed by the system 20at once. As shown, a site object can contain one or more page objectswhich, in turn, can contain one or more widgets (page elements 104),etc.

Each of the objects of the system 20 has a defined set of behaviors,properties and events. Once a site object has been created, the managercan create, update and delete styles, pages, content lists, database 58tables, workflows and digital assets 116 completely independently fromeach other. All object configurations are stored in the databasemanagement system 58 to enforce data integrity, versioning, search andretrieval.

After a site and its related objects have been configured, the system 20is ready to serve data to client browser 28 requests. When a browser 28requests data (e.g. a particular web page), the system 20 dynamicallycreates the data necessary for the web browser 28 to render the pageaccurately to the end user. This is done by traversing the object treeassociated with a given request, reading the correct version of eachobject from the database 58, binding all object data together and lastlycreating an HTML representation of the requested data. This techniqueallows all of a web site's objects to be treated and handled in a trulyobject-oriented manner on the server side while ultimately transformingthem into the structural elements (HTML, CSS, Image files) needed by aweb browser 28 to render and interact with end-users of the website.

FIG. 8 shows a graphical user interface 146 of the object editorcomponent 54, presented by the browser component 28 on the creator'sclient or the manager's client, with the assistance of the editor appletcomponent 50 if one exists, to enable the creator or manager to interactwith the object editor component 54 on the system 20 sever via the webserver 30 for the purpose of creating, modifying or destroying objectsinstantiating classes in the Website package 60 to create or manage awebsite.

The GUI 146 includes four main regions, a WYSIWYG design region 148, anobjects catalog region 150, an object property table region 152, and abutton pad region 154.

The catalog region includes an existing objects list 156 that catalogsall objects that currently exist to represent aspects of the website andan object palette 158 that catalogs all available classes forrepresenting aspects of a website for which objects may be instantiated.

The design region 148 provides a “what-you-see-is-what-you-get” area forlaying out the presentation aspects of a portion of a website, forexample placing and sizing content item objects 160 (“widgets”). Acontext menu 162 may be available to conveniently set various commonproperties of a selected one of the content item objects 160.

The object property table 152 provides a way to inspect and modify theproperties of a selected object, including objects that may not beconveniently represented in the design region 148 such as objectsinstantiating classes in the logic tier package 88 or the storage tierpackage 90.

The button pad region 154 provides a create button 164, a destroy button166 and a modify button 168. The create button 164 instantiates anobject selected from the object palette 158 and presents it forinspection and modification in the object property table 152. Thedestroy button 166 destroys the selected object. The modify button 168presents the selected object in the object property table 152 frominspection and modification.

Operation—Creating and Managing

In operation, a website creator 22 or website manager 24 creates ormanages a website through the GUI 146 described in FIG. 8. He can selectfrom the existing objects catalog 150 any of the objects that currentlyrepresent aspects of the website and the selected object will bepresented in the object property table 152 and, in the case of objectsthat can be represented by the WYSIWYG paradigm, selected in the designregion 148. The properties of the selected object can be modified in theobject property table 152 upon pressing the modify button 168.Alternatively, common properties of objects presented in the designregion 148 can be modified using the context menu 162.

Objects in the WYSIWYG design area can be selected, moved, resized,reflowed, etc. as directed by the mouse 32 or another user input device36. New objects can be dragged from the object palette 158 and placed asdesired onto the design area.

Pressing the create button 164 instantiates an object selected from theobject palette 158 and presents it for inspection and modification inthe object property table 152. Pressing the destroy button 166 destroysthe selected object.

In general, the object editor (presented in a standard web browser 28)hosts web pages and objects that form the user interface for creatingand managing websites, including pages, forms, tables and structuredcontent. All user interface elements within the object editor can behosted in an AJAX standard web browser 28 with no client-side plug ins.The object editor sends user input and receives and renders system 20responses via standard internet technologies, namely using the AJAXdesign pattern along with XHMTL compatible data, all transferred viahttp to a standard web server 30.

The web server 30 redirects all traffic from the object editor (or fromthe client's browser 28) to the system server 44. In simplest terms, thesystem server 44 is responsible for storing page and content datachanges received from configuration tool or from display, and returningdata changes in a manner that is compatible for a browser 28 to properlyrender it visually. All data changes are stored and retrieved fromrelational database 58. In this regard, the web server 30 provides aninterface operable to present representations of and functions as meansfor representing objects instantiating the plurality of hierarchicalclasses and to receive commands meant to one of: (1) instantiate a newobject, (2) destroy a presented object, and (3) change a property of apresented object. As embodied, this interface includes a user-interfaceand in fact a WYSIWYG user-interface, this representation includessymbolic representation and the commands include user-input.

The database server 46 performs standard database 58 tasks for thesystem 20, including: persistence and retrieval, indexing and search,transactions and rollback, enforcement of data typing and relationalintegrity as well as replication and archiving.

At a deeper level, the system server 44 consists of a complete orpartial set of the objects that define a website, with one topmostWebsite object for each user's web site, as well as objects for eachpage, table, content item, etc. that a given site may contain. Eachobject is derived from a set of hierarchical classes and sub-classesthat allow each object to:

-   -   store and retrieve their own configuration data from the        database 58;    -   store and manage an indefinite history of changes to itself such        that any previous state of itself can be restored should the        latest version of an object not be what a user wants;    -   render itself in a manner that is compatible with web browsers        28;    -   accept user input and process it in an object specific way; and,    -   define their own rules for how to handle user— or system 20        events. E.g., Mouse 32 clicks or record adds/updates.

In this regard, system server 44 provides and functions as means forproviding a plurality of hierarchical classes of objects, each of theclasses representing one aspect of the storage, presentation and logicof a website.

By using object orientation, new object in stances (or classes ofobjects) can be added to the system 20 or changed without affectingother objects in the system 20. Further, new objects can be derived fromexisting objects, thereby inheriting the features of the base objectwhile still allowing customization of the new object. For example, ablog object can be created that is based upon the content list object,thereby inheriting its storage and enumeration mechanism while allowingits own, encapsulated version control. In this regard, the databaseserver 46 stores and functions as means for storing objects as atraversable tree in accordance with the plurality of hierarchicalclasses.

Operation—Using

Referring now to FIGS. 2 and 9, when a website end-user 26 wants to usea website, he directs the browser component 28 on his device 36 to theweb server 30 to request presentation of a particular portion of thewebsite. That portion might be a webpage or a lesser portion, forexample in the case of AJAX techniques.

The web server component 52 on the web server 30 receives this requestand conveys it to the system server 44, where the object renderercomponent 56 receives it.

In a receipt and parsing step 170, the request for webserving is parsedto determine what is being requested and what portion of the website therequest relates to.

In a define webserving step 172, the objects that define the portion ofthe website relevant to the request are read by traversing the treehierarchy of the objects.

In a render webserving step 174, a webserving is assembled in HTML, CSSand JavaScript code that renders requested portion of the website asdefined in the relevant objects.

In a transmit webserving step 176, the webserving is transmitted to theweb server 30 for transmission to the browser component 28 of theend-user.

FIG. 10 illustrates an example traversal of the hierarchy of objectsdefining a webpage during execution of the define webserving step 172.In this example traversal, the overall website object is read 178, thenthe relevant page object is read 180, then in parallel two relevant pagewidget objects are read. With respect to one of the two page widgetobjects, a database view object is read 182, which ends the traversal ofthat branch. With respect to the other one of the two-page widgetobjects, a content list object is read 184, following which a contentitem object is read 186, which ends the traversal of the other branchand the relevant portion of the tree.

Thus the system server 44 renders and functions as means for rendering arequested portion of a website by traversing the corresponding portionof the object tree and generating a dynamic webserving in response tothe properties of the traversed objects.

In greater detail, referring back to FIG. 9, when the end-user requestsa given web page within a given site, the request (via an URL—e.g.,http://yoursite.com/page1) is transferred via the web server 30 and httpto the system server 44. Within the system server 44, the top-levelwebsite object locates requested page object from the object repositoryin the DBMS 58. Next, the “published version” of the page objectenumerates all of the published versions of each widget object(s)contained within the requested page object and tells them to createthemselves. Note that the page object has no knowledge of the internalsof each widget: their versioning information, data format on disk or howthey behave is all encapsulated within each widget object. Note alsothat any changes to the page (e.g., new/deleted/updated widgets) wouldautomatically be reflected each time a page is requested.

Once each page widget is created in memory, it is activated—allowingeach widget to run its own specific code and bind to its data. In thecase of content block widgets or “list viewers”, the data is retrievedby binding to and reading from content list objects. Each widget on agiven page binds its own data source; for example, with reference toFIG. 10, the page binds the content block widget and the other widget,and the other widget binds its data source.

Once a content list object is requested by a content block widget, itenumerates and creates its child objects, content item(s). Again, eachlist item is an object, encapsulating the knowledge of its internalversions and state information, as well as how to read, process andpresent its data within itself.

Once each page widget object has been created, performed itsinitialization, and received its data from it data sources (e.g.,content lists), it renders itself within the page container for viewingin the end-user's browser 28. That is, each widget dynamically producesthe HTML, CSS and JavaScript necessary within the requested page forrendering in the web browser 28 and processing of user input.

Lastly, the system server 44 sends the fully rendered page (or only thechanged portion of the page if the page is already loaded within theend-user's browser 28) back to the end-user's browser 28 forpresentation and user input.

Obviously, many modifications and variations of the present inventionare possible in light of the above teachings and may be practicedotherwise than as specifically described while within the scope of theappended claims. In addition, the reference numerals in the claims aremerely for convenience and arc not to be read in any way as limiting.
